Origin

To deign is to do something that you consider beneath your dignity, and the word is bound up with ‘dignity’. It goes back to Latin dignare ‘to judge to be worthy’, which was formed from dignus ‘worthy’, the source of dignity (Middle English), and dignify (Late Middle English), and the negative disdain (Middle English) ‘consider unworthy’.
